The Difference Between Grace & Mercy

There have been many times in my life when I have been confused regarding the meaning of Grace and Mercy.  One could almost say they are synonymous with each other and in fact, some scriptures seem to use them that way, or at a minimum don't make it clear.  Stop and ask yourself what is the difference between God's Grace, and God's Mercy.  For many, like myself, this was difficult for me to answer for many years. Some might say it is by grace we are saved and others might say it is by mercy we are saved.  It is the same thing?  This video discusses the true difference between Mercy and Grace.
